I have been having troubles in recent weeks with several herbs failing. This has happened with Sage and Rosemary, where parts of them have just faded and then died. The Rosemary turned brown and the Sage wilted. There are no signs of bugs, and there is adequate rain and moisture. There are also no splotches on the leaves of the sage like you'd have with a fungus or other type of disease. This is the second time for the Sage to have this problem and the first for the Rosemary.
Anybody have any ideas?
